Troubleshooting Common Issues with Granule Packing Machines

Granule packing machines are essential for automating the packaging process of granular products, such as coffee beans, sugar, salt, and pet food. However, like any equipment, they can encounter issues that affect their efficiency and productivity. This article provides a comprehensive troubleshooting guide to help you identify and resolve common problems with granule packing machines, ensuring smooth and optimal operation.

Machine Not Sealing Bags Properly

– Loose sealing jaws: Check if the sealing jaws are loose or misaligned. Tighten or adjust the jaws as necessary.

– Damaged sealing wire: Inspect the sealing wire for damage or wear. Replace the wire if it is torn or burnt.

– Incorrect sealing temperature: Verify that the sealing temperature is set correctly for the type of film being used. Adjust the temperature accordingly.

– Air trapped in the bag: Ensure that the bag is fully opened and there is no air trapped inside before sealing.

No Product Discharge or Intermittent Discharge

– Product hopper empty: Check if the product hopper is empty and refill it.

– Clogged discharge chute: Inspect the discharge chute for any blockages. Remove any obstructions or adjust the hopper angle to improve product flow.

– Damaged conveyor belt: Check the conveyor belt for damage or wear. Replace or repair the belt if necessary.

– Faulty vibratory feeder: Ensure that the vibratory feeder is functioning properly. Adjust the speed or amplitude of the feeder or replace it if needed.

Machine Not Filling Bags to the Correct Weight

– Incorrect scale calibration: Verify that the scale is calibrated correctly. Calibrate the scale using certified weights and adjust the settings accordingly.

– Loose load cell: Check if the load cell is loose or damaged. Tighten or replace the load cell as necessary.

– Product spillage: Ensure that there is no product spillage during the filling process. Adjust the bag alignment or modify the filling mechanism to prevent spillage.

– Overloading or underloading: Adjust the target weight setting on the machine to match the desired filling weight.

Excessive Bag Leakage or Tearing

– Sharp film edges: Inspect the film for any sharp or rough edges. Replace the film roll or adjust the film tension to prevent tearing.

– Incorrect bag size: Ensure that the bags being used are the correct size for the machine and the product being packed.

– Faulty bag forming system: Check if the bag forming system is functioning properly. Adjust the forming settings or replace damaged parts if necessary.

– Product bridging: Prevent the product from bridging or clumping inside the bag by optimizing the filling process or adding anti-bridging agents.
